ctx-absorb

name	_ctx-absorb
description	Extract and apply deltas between two directories of the same project. Use when merging results from a parallel worktree or separate checkout where git push/pull isn't practical.
allowed-tools	Bash(git:*), Bash(diff:*), Bash(ls:*), Bash(patch:*), Read

Extract changes from a "future" directory and apply them to the "present" working tree. Complement to ctx-worktree: worktree splits work apart, absorb merges results back.

When to Use

• Merging results from a parallel worktree back into the main checkout
• Applying changes from a separate checkout (different machine, USB copy)
• User says "absorb", "bring changes from", "merge from folder"
• Two copies of the same project need their deltas reconciled

When NOT to Use

• Directories are on a shared git remote — use git pull / git merge
• Worktree is managed by git — exit or delete the worktree directly
• Directories are different projects (no common ancestry)

Pre-flight Checks

1. Validate directories exist:

   ls "<present>" "<future>"
   

2. Same-project fingerprint — at least one must match:

   • Same go.mod module path, or same package.json name
   • Same .context/CONSTITUTION.md exists in both
